There are two primary ways that infectious agents, like bacteria and viruses, in your water can be neutralized. The first treats your water with antiviral and antibacterial compounds that sterilize infectious agents. These compounds work by maintaining specific volumes, exposure times, and proper dispersion – all variables that are vulnerable to both human and machine error. Ultraviolet light, another agent used to sterilize bacteria, is an even more difficult treatment to maintain. This is why sterilization on its own is not a sufficient treatment method.
